JOHN E. CONZELMAN, OF ST. LOUIS, MISSOURI, ASSIGNOR T0 UNIT CC NSTRUCTION COM- PANY, 0F WILMINGTON, DELAWARE. A CORPORATION OF DELAWARE CONCRETE CONSTRUCTION.

Specification of Letters Patent.

Application filed November 16, 1909. Serial No. 528,275.

To all whom it may concern:-

Be it known that I, JOHN E. CONzELMAN, a citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented certain new and useful Improve ments in Concrete Construction, (Case H,) of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to concrete building structures and refers particularly to a construction in which superimposed columns are joined to form a rigid and secure structure, and horizontal floor and ceiling members are used and are supported at the junction points of said columns; to a construction in which concrete slabs are used for ceilings and floors, and are supported at their corners or centers by uprights or columns; and, also, to a construction in which a concrete column is supported by a foundation.

It is the object of this invention to provide means for uniting concrete building elements to form a strong and durable structure, and, also, to provide the uniting means with reinforcement which greatly strengthens the juncture of said elements.

In the drawin s forming part of this specification, in W ich like numerals of reference denote like parts wherever they occur, Figure 1 is a plan view; Fig. 2 is a sectional view on the line 2-2, Fig. 1; Fig. 3 is a plan view; Fig. 4 is a sectional view on the line 44, Fig. 3; Fig. 5 is a plan view; Fig. 6 is a sectional view on the line 6-6, Fig. 5; Fig. 7 is a plan view; Fig. 8 is a sectional view on the line 8-8, Fig. 7; Fig. 9 is a plan view; Fig. 10 is a sectional view on the line 1010, Fig. 9; Fig. 11 is a plan view; Fi 12 is a sectional view on the line 12-12, Fig 11; Fig. 13 is a plan view; Fig. 14 is asectional view on the line 14-14, Fig. 13; Fig. 15 is a plan view; and Fig. 16 is an elevatlon of Fig. 15.

It is to be understood that the slabs and columns hereinafter referred to may be made at any desired place, but preferably away from the location where the building in which they are used is being constructed.

For the purpose of illustration all-concrete columns are depicted in the drawings, but reinforced concrete columns or metal columns can be used, and said columns can, also, be of any size or shape.

Each slab 1 is moldet. with any desired configuration and can either be a flat slab or said slab can be provi led with a flange 2 on the under side there )f. The corners 3 of each slab may rest on a shoulder 4 of the cap 5 of a column 6 am. against stud 7 of.

such column, 'in the man ner shown in Figs. 1, 2, 3, and 4. The stuc 7 may be omitted and a corner 3 of each slab may be supported by a column 6, a: shown in Figs. 7, 8, 9, 10, 13, and 14, or iach slab 1 may be supported at or near its zenter by a column 6, as shown in Figs. 5, 6, 11, and 12.

In Figs. 1 and 2 the c( rner 3 of each slab 1 is provided with a recess 8, which is adapted to fit against str 6. 7 and to register with an adjacent recess 8. Said recesses form the sides of an opeii space 9 above the stud 7. The stud 10 and shoulder 11 are formed on column 12. Said shoulder 11 rests on said corners 3 a: 1d stud 10 projects into space 9. Said stud 10 preferably fits closely to the sides of sai d space 9, whereby the column 12 is prever ted from any side motion. Said column 12 is provided with a slot 13 or a plurality of such slots which preferably intersect each other and which can either extend transv :rsely through said column as shown in Fig s. 1 and 2 or they can extend diagonally thereof as shown in Figs. 3 and 4.

Each rod 14 is bent into a U-shape and the ends thereof are set it the top of column 6. The bent portion 01 each rod 14 projeets above column 6 and extends preferably across the bent portion of another rod 14. Said rods 14 occupy suc 1 positions relative to slots 13 that each rod L4 will enter one of said slots 13, when colu nn- 12 is placed in position over column 6.

Reinforcing rods or be rs 15 are embedded in the lower part of each slab 1. Each flange 2- is reinforced with a rod or bar 16 which is embedded in the lower part of sai flange, and, adjacent the end thereof turns upwardly into the upper part of said flange. Said rod or bar 16 may ither protrude into space 9 in the manners iownm Figs. 1, 2 3, and 4, or it may end adjacent the end of flange 2 and lie wholly within said flan e. Short rods or bars 17 are embedded in t e upper part of each slab and extend preferably over the column up on which each slab rests.

In uniting the elemerts hereinabove de- Patente d Nov. 14, 1911.

scribed into a concrete structure as shown in Figs. 1 and 2, the column 6 is set in position, then each slab 1 is placed so that a corner 3 rests on shoulder 4 and against stud 7, and column 12 is set in such position over column 6 that shoulder 11 rests on cor ners 3 and stud 10 enters space 9. Each slot 13 communicates with said space 9 and receives a rod 14. Each slot 13 is covered with a board (not shown in the drawings). Grout or wet concrete is then poured through an opening left over one of said boards and fills the space 9 and each slot 13. Said grout or wet concrete, being allowed to set in space 9 and in each slot 13, adheres to the sides thereof and, On account of the presence of the rods 14 in said slots, the union of the elements is greatly strengthened and a rigid and integral juncture is obtained.

In Figs. 3 and 4, the shoulder 4 of column 6 is provided with a cut-away portion 18. An indentation 19 is formed in each side of corner 3 and, when slabs 1 are in place each indentation registers with an adjacent indentation and forms therewith a slot 20. The rods 21 are bent preferably into the shape shown in Fig. 4 and each end thereof is set in the top of column 6. When slabs l are placed in position each corner 3 will rest on shoulder4 and against stud 7 which in this form extends only a short distance above column 6, and each slot 20 is disposed opposite a similar slot 20. Each pair of oppositely-disposed slots 20 receives a rod 21. Rods 14 are set in column 6 and project in such manner above said column that each of said rods 14 will enter a slot 13. Said slots 13 preferably extend diagonally through column 12. A so-called form (not shown in the drawings) is placed at each corner of column l2'so that each slot13 is covered. Each slot 20 is covered with a board and the sides of each cutaway portion 18 are, also, covered with a form to prevent the grout or wet concrete from running out of the same. An opening is left in one of said forms covering a slot 13 and grout or wet concrete .is poured therethrough. Said grout or wet concrete runs into and fills each cut-away portion 18, each slot 20, space 9, and each slot 13 and is allowed to set therein, whereby the elements are united strongly together and form a rigid and integral structure.

In Figs. 5 and 6, the stud 7 is omitted and the slab 1 is supported at its center by column 6.

Rods 15 are embedded in the lower part of said slab and rods 17, which are located preferably. over column 6, are embedded .in the upper art of said slab. A pair of slots 22, each of which preferably intersects the other, is formed in said slab and extends through the portion which rests on column 6. Rods 14 are set in column 6 in the manner hereinabove described, and, when said slab is placed upon said column each rod 14 will enter a slot 22. The stud 10 of column 12 is omitted and the base of said column rests upon slab 1. Each slot 13 occupies such position in column 12 that, when said column 12 is placed over column 6 and upon slab 1, each rod 14 will enter a slot 13 and each slot 13 will register with a slot 22. Said slots 13 are boarded up as hereinbefore described and grout or wet concrete which is poured therein fills each slot 22 and each slot 13, thereby forming an integral structure and a strong juncture.

In Figs. 7, 8, 9, and 10, the column 12 is omitted and a corner 3 of each slab 1 rests on column 6. In Figs. 7 and 8 each side of each corner 3 is provided with an indentation 23. When said slabs are placed in position on said column 6 each indentation 23 registers with an adjacent indentation and forms therewith a slot 24. Each slot 24 is preferably located opposite a similar slot 24. Rods 14 are set in column 6 so that each of said rods will enter a pair of oppositelydisposed slots 24. Said rods 14 extend preferably to a short distance below the level of the top surface of each slab 1. Each slab is provided with a reinforcing rod 15 in the lower part thereof and with reinforcing rods 17 in the upper part thereof. Said slots 24 are filled with grout or wet concrete which is allowed to set therein, thereby uniting the slabs and the column to form a rigid and unitary structure.

In Figs. 9 and 10, each corner 3 is provided with a slot which extends preferably diagonally into said corner. When said corners 3 are placed on column 6, each slot 25 will occupy a position opposite another slot 25, and each rod 14 will enter a pair of oppositely-disposed slots 25. The slabs 1 and column 6 are united to form an integral structure by filling said slots 25 with grout or wet concrete and allowing the same to set therein.

In Figs. 11 and 12, the colimin 12 is omitted and the slab 1 is supported at or near its center by a column 6. The slots 22 are formed in said-slab in the same manner as hereinabove described in the description of Figs. 5 and 6. Said slab is placed'upon column 6 so that each rod' 14 will enter a slot 22 and said slots 22 are filled with grout or wet concrete which is leveled off with the top surface of said slab and allowed to set. Said slab is thus united with said column 6 into a rigid and integral structure.

In Figs. 13 and 14, each slab 1 is supported at a corner 3 by column 6. When said slabs 1 are all similarly placed upon column 6, a space 26 is left between each two adjacent slabs supported by said column. The column 12 is placed so as to rest upon each corner 3 and, also, in such position that each column 12 fills with grout or wet concrete which enters the same from spaces 26. Said grout or concrete is allowed to set and forms a beam (not shown in the drawings) in each space 26, and by reason of the concrete filling the space under column 12, the beam .1s formed continuous over column 6 and may be all-concrete or reinforcing rods may be set in said beam, and said elements are united into a strong and integral structure.

In Figs. 15 and. 16 a foundation 27, which is preferably concrete, is shown. Rods 14 are set in said foundation and each projects above the same into a slot 13 of a column 12, when said column is placed in position on said foundation. Slots 1?) are covered with boards as hereinabove described and are filled with grout or wet concrete which sets therein and secures said column rigidly to said foundation.

It is to be understood that the monolithic, unitary concrete structure herein described is suitable for use not only in build ings and not only in the floors, ceilings, walls, and other parts thereof, but, also, in the construction ofbridges and all other construction in which it may be desired to use the same.
